The importance of mental health and well-being has been on the rise lately. People across the globe have realised that mental disorders are as important as physical illnesses, if not more. Mental disorders can lead to severe physical symptoms, causing physical diseases in future if not treated at the earliest.

Are you curious to know more about the physical symptoms of mental illness? Then, read till the end of this article for a detailed overview.

There is no denying the fact that the mind controls the body. When your mind senses something unusual, it starts giving away signals for your body to respond to it.

• For instance, there are two stress hormones, adrenaline and cortisol, and your body fills with these in stressful events, thereby increasing heart rate and blood pressure.
• Apart from that, the effects of mental health on physical health are also visible, as these hormones can harm your digestive and immunity systems. This causes a loss of physical energy till the threat is visible. Then, your body returns to normal when the trigger no longer threatens the mind.
• Moreover, chronic stress causes your cortisol and adrenaline levels to be high constantly for a long time, and it might decline the ability of your organs to function correctly.
• Another issue comes from mental illnesses like anxiety and depression, which can potentially lower your body's pain tolerance
• There are parts of the brain responsible for pain reception, and the two neurotransmitters, serotonin and norepinephrine, have the role of pain signalling. So when they fail to act appropriately during mental health issues, their body starts feeling more pain.

Thus, you can see that there is a clear link between body and mind, which makes the body vulnerable to mental health issues. Here are some physical symptoms of mental disorders to help you get a better idea.

Now that you know the symptoms, it will be beneficial to understand the impact of mental health on physical health. Here are some of the most common mental health issues and their possible effects on your physical health.

1. Worsens Chronic Conditions

Anxiety, panic and depression are some of the most chronic mental disorders. As they affect the brain and hormones for longer, they are more likely to cause serious physical illnesses. For instance, depression can cause asthma, diabetes, cardiovascular diseases, cancer, and arthritis.

Schizophrenia, a psychological condition, can negatively affect your body, and its patients have a higher risk of suffering from heart and respiratory diseases. Moreover, mental health issues further worsen the condition of patients suffering from physical illnesses. For instance, cancer and heart disease patients have a higher mortality rate if they suffer from depression.

2. Causes an Unhealthy Sleep Patterns

Mental health disturbance can cause sleep problems for most people. Depression and anxiety, for instance, can cause insomnia and sleep apnea. Insomnia makes it difficult to fall asleep at night, causing sleep deprivation. This, in turn, causes fatigue, dizziness and nausea during the day.

On the other hand, sleep apnea can lead to respiratory problems, causing breathing trouble while sleeping. In addition, most mental health issues like depression, anxiety, and bipolar disorder can cause sleeping problems, disrupting a healthy sleeping pattern.

3. Increases Smoking Tendencies

People suffering from mental health issues are more likely to smoke cigarettes than those who do not suffer from such disorders. This is because they suffer from mental health issues like depression and might experience lower levels of the chemical dopamine. The nicotine content in a cigarette can trigger the production of the chemical dopamine, which affects the positive feelings in your brain.

People smoke to relieve symptoms of depression. However, it can have various adverse effects. For example, excessive tobacco smoking can cause multiple physical disorders like heart disease, lung disease, cancer, diabetes, stroke, and chronic obstructive pulmonary disease (COPD).

4. Hampers Digestive System

Clinical researchers have found a clear link between the mind and the gut. For example, stress and anxiety can cause various digestive issues like abdominal cramps, heartburn, or loose stools. Moreover, depression and anxiety can cause diarrhoea, constipation, bloating, pain, and an upset stomach.

The enteric nervous system (ENS) communicates with your brain using hormones, where exchange occurs between the gut and the immune system. It affects the microorganisms living along your gut that help in the digestion process. As they fail to function, you are more likely to experience indigestion, loss of appetite, nausea, etc.

5. Reduces Muscle Strength

Muscle tension is a common issue arising from mental health issues. Chronic stress is a major problem for this issue. It causes catabolism of muscle proteins, which decreases the strength of muscles. Additionally, testosterone and growth hormones increase the rate of protein synthesis. However, chronic stress can hamper this process.

Moreover, stress also causes muscle tension, and it causes your body muscles to be in a constant state of guardedness. If your muscles stay taut and tense for a long time, they will trigger other physical reactions. Besides that, fear and stress of muscle pain and injury can also affect the recovery time and process.

6. Damages Immune System

Glucocorticoids regulate the immune system along with cortisol. The communication between immunity and the HPA axis is essential to reduce inflammation. However, this process is hampered in an extremely stressful situations. This results in multiple health issues like fatigue and metabolic disorders like diabetes and obesity.

Cortisol is also responsible for increasing the level of energy fuel while mobilising the glucose and fatty acids from the liver. Therefore, stressful events can cause an increase in cortisol and energy levels, and this increased energy might cause fatigue and dizziness later when such an event is over.
